` HE'ssELisiAN,` a citizen fof the i Kingdom of'- I specification. i,

vBe 'it known that I, KNU'i 'Joins ELIAS Sweden, lr`esi diii'g at,I Saltsj -1 Storngen, Stockholm,Swedeinliave invented ner1 and useful Improvements 'in' lnternal-Combustion'Engii'ies',"l of`ivh'ich the following'is a This invention relatesto internal combustion engines and-more especially of the kind in'Qwhich the fuel-isintrodiiced ,intothe combustionchamber or chambers-of the engine by'i means oaf coinpressed` air or.any other gaseous avent under pressure.

'chamber or chambers byfmeans of compressedair, or'the like'. `In such engines it is not sullicientinorder to facilitate the starting to put thecombustion chamber or chariibers in comniunication with Ithe 'atmos phare, bu'tit is also necessary to cut oi the supply of compressed air, or the lilcegtp the saidfchamberor chambers. For this pui'- pose'l combine amanually operated exhaust valve and aluid pressure inlet valve `with means'for operating said .valves simulta- 'neouslyin such a niaiin'ertliat the said fluid pressure inlet valve isA closed or vput out of operation when the manually operated exliaustvalve is opened.

In the accompanying drawing I have shown one embodiment of my invention.

Figures l and A2-sliow sectional views of the improved valve device with the parts in two different posit-ions.'

Referring to the drawing, 1 indicates the cylinder of the engine and 2 an exhaustvalve'whichnormally is kept closed by a spring 7 (Fig. 1) and when opened puts the combustion chamber of vthe engine in communication with the atmosphere (Fig.

2).' The said valve 2'may b e operated by' ineens of a' hand `lever 3, or, the like, on

'which' is journaled atWo-armed lever 4 which in 4any Well known manner is oper* e.. `4 I N'aEnNAL-COMBUSTION ENGINE.'V

ated from any one of the moving arts offthe -engine lso as to' open an inlet va ve 50u"l 'required times,said valve serving to` admit fuelund fluid under pressure to the cour bustion` chamber. The fluid under pressure and fuel are admitted to t-lie valve-ch. ber 8 through a pipe 9. sThe pivot 6 ofth l is .located eccentrically in relation to theV pivot' of the hand lever 3 in such a manner l ever that the lei'er-fwvhen the hand lever. is

turnedl from the. position in Figfl'fto thel position in` Figl`2 will be inactive on ac"` 'count of its pivot changing its position.

Then the hand lever 3 is turned down into the position shown in Fig. 2 it strikes the 'stein of the valve 2 and opens (the latter, so tliatytlie pressure eventually remaining in the combustion chamber escapes through the valve2. At the same time the`va1ve 5 is closed under the actionPot its spring 10 and will remain closed until the hand lever is -4 turned backinto the position shown in Fi l, so that. no'liuid under pressure is a mitted to the combustion chamber during the period of starting.

When starting theenginc, the'exhaust y valve 2 is held o en and the inlet valve 5 is kept closed inci ental to the initial movementof the piston, and then subsequent. to the said movement of the piston the hand lever 3 is turned back into vthe position shown in Fig. 1 resulting in the 1exhaust valve 2 being closed, by its spring 7- and the valve 5` being released and adapted to work in the usual manner.

The device described may also suitably be' used when it is necessary to.increase in the air receivers the air pressure used for introduciiig the fuel into the engine. In .such case the valve 5 is putoutof operation in 'the manner described until the. correspondvnig air pump has introduced the quantity of air required in the corresponding air receiver. Finally the device may in engines having a plurality of cylinders be used tu put one or more cylinders out of operation in order thereby to"have the engine run at a lower speed than the normal one.

The handl lever should suitably be spring actuated, asis shown,y in such a manner thatitautomatically i'etakes the position shown 11i Fig. 1 whenreleased.

Obviously the device described above may A vbe modified in details Withoutfdeviating l11o from the princi le of the invention.

Having now escribed my inventioii'what i I claim as new and desire to secure by Let-l ters Patent is:

In an inter-nal cmnbustion engine, the combination of a cylinder containing an explosion chamber an outwardly seating exhaust valve suitably guid'eclvin the cylinder and extending' outside the same and having an abutment on its outer portion, aV spring interposed between thesaid abutment and the cylinder and normally holding the exhaust valve to its seat, a fluid-pressure inlet valve having its eduction opening in constant communication with the explosion chamber; said valve extending outside the cylinder and having an enlargement on its outer portion, a spring bearing at one end against the outer end of said valve, an abutment fixed to the cylinder and arranged at the opposite end of thespring with reference to said valve, a two-armed lever having the opposite direction, and a pivot carrying the two-armed lever and carried by the han lever and located eccentrieally in relation to the pivot of said'hand lever, all substanl tially as and `for the purpose set forth.

In. ,testimony that I claim the foregoing as my invention, I have signed my name 4m presence of two subscribing witnesses.
